HARRISON OGBOIiN, OF-GREENS FORK, INDIANA.

IMPROVEMENT IN WEATHERSTRIPS.

Specification forming part of Letters Patent No. 40.911, dated December l5, 1863 antedated December 6, 1863.

To all whom it may concern:

Be it known that I, HARRISON OG BonN, ofA Greens Fork, in the county oil/Vayne and State of Indiana, have invented a new and usefull Weather-Strip or X/Vater-'lightI Threshold for Outside Doors; and I do herebjdeclare that the following is a full, clear, and exact description of the construction and operation ofthe same,refe-rencel being had to the accompanying drawings, making 'a -pa`rt of this specifica tached to doors by means of screws or nails, -as shown at I in Fig. l. A is the ordinary door-frame. B is the door to which the strip is attached. C is the curved or bentpiece which gees above piece D. D is the lower or vibrating piece. E is the ordinary door-sill. F is a piece of metal which is .fastened onto door- .i rame for the piece D to strike against toclose it down onto the sill. Gis a bolt or rivet of apeculiar shape, which holds the pieces G and D in their proper position, both when the door is open and closed. H H are springs that are fastened to the under side of piece C, which bear against piece D, so that the moment the door lis opened the pressure of the springs on the upper side of piece D depresses it, thereby elevating the lower edge of piece D so that the door may open. I is the screw-heads in Fig. 1.

In the foregoing like letters refer to simzlar parts i'n the ditt'erenttigures or drawings. The bolts G G are firmly fastened to piece G in any convenient manner, but play loosely and freely in piece I) inlioles (two or more) made for tle purpose.

, Having described the construction of my invention, l willproceed to describe its operation.

When tlie-door is thrown open, the springs II II act upon the lower piece, D, from the fact th at they are fastened to the upper piece, C, and are curved oit' from it, in such a inanner as causes the lower edge of piece D to rise up from the sill and above the iloor, so

.that it -will be as high or higher than thc bottom of the door; when the door may be swung freely back and forth, and carry both strips with it. When the door is closed, the lower edge of piece D comes in contact with the' edge of the sloping piece F, when the pressure causes it to slide down to the sill, thus closin g thelower part of the door in such ainanner as to make it water-tight, in which position it willremain as long as the door is kept closed, when if the door be opened the spring throws up the piece D, as already described.

Having described the nature, construction,

and operation of my invention, what I claim therein as new and useful, and desire to secure by Letters Patent, is

The bolts G G, in 'combination with curved piece C, piece D, and springs H H, the Whole being arranged, constructed, and 'operated in `the vmanner and for the purposes set forth.
